Abstract
A circular polarized Multi-Beam Antenna (MBA) with 3:1 bandwidth is described. The enhanced Log Periodic Dipole Array (LPDA) feeds are used to enlarge MBA´s 27dB coverage region and improve antenna´s maximal gain. The Wavelength-Scaled Array (WSA) is applied to restrain gating lobes. Compared with the single LPDA feed, the 27dB coverage region of this antenna is much lager and the maximal gain is about 3dB higher.
